To all whom it may concern:

Be it known that I, OREN FISH, of Cleveland, in the county of Ouyahogaand State of Ohio, have invented certain new and useful Improvements inthe Method of Manufacturing so-called Chisel-Brushes, and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to an improved method for manufacturing so-calledchisehbrushes, in which is employed a band in which the bristles areassembled with, preferably, a removable plug placed in the band for thebutt-ends of the bristles to rest on, such plug having a tapering orbeveled end corresponding with the desired chisel-point of thebrush,whereby with bristles of equal length the fag ends of the bristlesare brought in the desired form for the brush. Next, the bristles arebound, removed from the band, and the butt-end of the bundle is squaredoff, leaving the bundle of bristles in condition for attaching to thebrush-handle,to the end that with such method and mechanism employed. agreat saving is effected in the initial cost of the brushes and thelatter are made uniform. In manufacturing brushes the fag-ends of thebristles, be-' ing the valuable portion for wear, are left intact, andany trimming that is done should be at the butt-ends of the bristles.Heretofore in manufacturing this class of brushes the practice has beento bind thebristles for a brush in a bundle having the fag-ends even,and then to trim off thebutt-end of the bundle to the shape desired forthe chisel end-of the brush, after which the shorter bristles of thebundle were slid endwise to square off the butt-end of the bundle, thustransferring a chisel-point to the flag-end of the bristles, after whichthe bristles were fastened to the handle. Such practice was slow andexpensive,requiring the labor of skilled workmen, and even then thebrushes were not uniform, it being exceedingly difficult to hold all thebristles in their proper relative position while shifting them endwiseto square off the buttend of the bundle. I have, therefore, de-

vised the method, as illustrated in the accom- 5o panying drawings.

Figure l is a view in perspective of a completed chisel brush. Fig. 2 isan elevation in section. Fig. 3 is a plan, and 'Fig. 4 is a view of thebristles in position to be attached to the handle.

A represents a band, usually of metal, and of suitable size forassembling therein the bristles for a brush, and corresponding insection with the desired form of such brush. 7 6o Bis a plug, usually ofwood, the reduced end of which is made to fit easily in the band A. Ashoulder, B, of the plug abuts the lower end of the band, so that theplug always extends the same distance into the band. The lower end ofthe plug is usually left square, and is of considerable size, so thatwhen the plug and band are assembled they will stand upright on the endof the plug. The upper end of the plug is beveled off on opposite 7oedges, or tapered to form the point b, the lat ter corresponding withthe desired chiselpoint of the brush.

Bristles, as they are bought in the market, are assorted to length, andbristles O are assemblcd in the band A, the butts of the bristlesresting on the end of the plug. By reason of the pointed or beveled endI) of the plug,to which the butts of the bristles conform, the fagendsof the bristles are made to come spond with the point I) of the plug,thus forming a chisel-point, c, for the brush. The bristles G are nexttemporarily bound by cord or band a above the band A to hold them inplace, after which the bundle of bristles is removed from the band andthe butt-end of the bundle is squared off, thus leaving the bundle ofbristles in condition to be attached to the handle in the ordinarymanner.

The plug B being removable any number of plugs having different shapedends I) may be used in the same band A; otherwise the plug, or a bottomof the desired form, might be rigidly attached to band A. The savingthus effected over the old method aforesaid is con- 5 siderable, and thebrushes are made uniform.

N o skilled labor is required, and the only trimming of the bristlesrequired is to square off the butt-end of the bundle, and this may bedone in a moment.

XVhat I claim is- The herein-deseribed method in the menu- 5 facture ofso-called chisel-brushes,consisting. essentielly,in assembling thebristles in a band with the butt-ends of the bristles resting on a plugor bottom, the latter corresponding with the desired chisel-point of thebrush, binding 10 the bristles thus assembled, and then removing thebristles from the head and squaring off the butt-end of the bundle,substantially as set forth.

In testimony whereofIsign this specification, in the presence of twowitnesses, this 7th day 15 of July, 1887.
